That strategy requires you to have good timing on the market. But the problem is, by doing so, it will make you emotional and you will be prone to make mistakes making you lose some of your money.
If you want the best strategy for ordinary investors like us, "buy the dips". If you have a job you should save 20% of your monthly salary and make that available to buy when Bitcoin's price is falling.
I really appreciate a very good advice. That is what I think so. I know a friend too, that became sad because the value of bitcoin fluctuates a lot. He is so eager to trade the bitcoin he have now but he can not do anything but wait. Truly is, we sometimes become emotional in times like this. But if we have a good capital we can be happy since we can buy coins and sell them in the most appropriate time. Therefore, buying coins at its lowest value and selling them at its highest value.
